Abstract

Quality and limitations of current quantitative precipitation
simulations are determined using the Deutschland-Modell
of Deutscher Wetterdienst (DWD). The model independent
validation data comprise the regular rain-gauge network of
DWD, taylored composites of an international radar
network, Doppler winds from the DLR research radar,
and meteorological timeseries at a ground station. Area
skill scores are compared for convectively dominated as
well as more synoptically forced situations in the northern
Alpine region. Inspection of the temporal evolution of the
components comprising the atmospheric water budget and
of the precipitation partition gives insight in the different
nature of excitation mechanisms of heavy precipitation. The
simulations are found to exhibit growing potential for
follow-on hydrological applications, while a real breakthrough
appears to necessitate the coming generation of
non-hydrostatic operational forecast models with increased
spatial resolution.
